Specification of Letters Patent. Patented Aug, 112, R919.

Application filed August 17, 1916. Serial No.'115,534.

To all whom it may concern:

Be it known that I, JOSEPH H. ORDWAY,

a citizen of the United States, residing at Brookline, in thecounty of Norfolk and State of Massachusetts, have invented certam Improvements in Machines for Use in Manufacturing Stifl'eners' for Boots and Shoes, of which the following description, in

connection with the accompanying drawings,

is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to the manufacture of stiffeners for parts of the uppers of boots and shoes and is herein illustrated in connection with a machine for applying stiffening material to box toe blanks.

In the patent to Knipe No. 1,127,641 there is disclosed a box toe or shoe boxing made by saturating with melted wax all of a blank of fabric except the margin thereof, said margin being left unsaturated so as'to facilitate the stitching operation and the pulling over and lasting operations in which said margin is gripped by pincers. Hitherto 'it' cause the wax to permeate the blank. The

general object of the present invention is to obviate this hand operation and at the same time to cause the blank to be permeated thoroughly by the stiffening material.

' One feature of the invention comprises in a machine of the class described, a reservoir for stiffening material, a member against which the blank may be pressed, a carrier having a material-holding depression in its upper face, and means for causing the carrier to raise material from the reservoir and apply it to the blank. With this construction a definite measured amount of material is forced into each blank to impregnate it.

It isdesirable that the blank be thorr oughly impregnated with the stiffening mapregnation can then be obtained by applying stiffening material to both sides of the blank underpressure. Another feature of the invention comprises a pair of opposed carriers, means forsupplying said carriers with 'stiifening material, and means for causing said carriers to press material into both sides of a blank. These and other features of the inventio including certain details of construction and combinations of parts will be described in connection with an illustrative machine and pointed out in the appended claims. Referring now to the accompanying drawin l igure 1 is a perspective of a machine in which the present invention is embodied;

Fig. 2 is a detail partly in section showing in full lines the normal positions of the carriers with respect to the level of the stiffening material and in dotted lines their positions when one is applying stifiening material to the other;

Fig. 3 is a detail principally in elevation of the clutch and cams; and

Fig. 4 is a perspective of a piece of work which has been operated upon.

Mounted on a suitable frame is a reservoir 5 for the stiffening material. This material is solid at ordinary temperatures and in the illustrative machine I is melted and maintained in liquid form by electric heat units, not shown, which are carried in the walls. of' the reservoir and to which electricity is conducted through wires 7. The

particular means for applying heat to the reservoir is immaterial, and the specific -means used will not be described further.

is adjustably held in place by a screw bolt 17 threaded through said carrier and contacting with said rod. Normally this carrier is located beneath the level of the stiffening material; and'its upper-operative face is concave to provide a pocket or depression which is designed to hold a small amount of stiffening material when the carrier is forced up out of the liquid. Located above the 23, said carrier having stretched over its op- .erative face a piece of fabric 25 held in place by a band 27. A heat unit of suitable form to which electricity may be led'by w1res 29 keeps this carrier at a proper temperature.

Located between the pair of carriers and in their paths of movement is a hollow support 31, the outside dimensions of which are less than those of the upper carrier 19 while the inside dimensions at the extreme top are slightly greater than those of the lower carrier '15.. The opening through the support 31 is tapering, and a guide-33 1s fastened to the lower edge to assist in guiding the surplus liquid back into the reserv oir.

In the illustrative machine, which is designed to operate upon box toe blanks, the outline of the face of the lower carrier is similar to but somewhat smaller than the outline of the blank so that the stifiening material will be applied to the under side of the middle portion of the blank as indicated at 35 in Fig. 4, leaving the margin 37 in its original state. The upper carrier has the same general outline as the lower carrier but is slightly larger so as to contact with the rim of the hollow support 31.

Assuming that the parts 'of the machine thus far described are 1n the positions shown in full lines in Fig. 2 and that the upper carrier has been loaded with stiffening material, a box the blank is placed upon the hollow support 31 with. its margin, which is not to be saturated, projecting beyond the edge or rim of said support. The two carriers are then moved into approximately the positions shown in dotted lines, the upper carrier reaching its position first and clamping the blank firmly in place, and the lower carrier reaching its operative position a moment later. The middle portion of the blank is thus gripped firmly, and the stiffening material forced thoroughly into the interstices of the fabric. The carriers then return to the full line positions to permit the operator to remove the blank and to prepare for the application of another load of stiffening material to the u-p-per carrier. The cycle of movements, which has been described above, is then repeated but with no blank in place, the lower carrier supplying stiffening material to the upper carrier as shown in dotted lines in Fig. 2; and the parts come to rest in the full linepositions preparatory to operating upon a second Referring now more particularly to Figs. 1 and 3, the mechanism by which the carriers are operated will be described.

The square rod 23, to which the upper carrier is fast, slides in a bearing in a stationary bar or bracket 39. A rocker arm 41 angularly movable about a stationary rod 43 is attached at its forward end by a link 45 to the rod 23 and at its rear end is pivoted to an upright rod 47. The loWer end of this rod 47 passes through a slot in a cam lever 49 and is held in place with respect to this lever by a collar 51, a second collar 53 and a coiled spring 55 located between the collar 53 and the cam lever 49, the purpose the driving shaft 65. llhese two cams are rigid with each other as well'as with a gear 67 and a clutch member 69. A second clutch member 71 slidably keyed to the shaft 65-is provided with a groove to receive a pin 73 on a lever" 7 5,'the hub of which is fast to a rod 77 loosely mounted in bearings in the frame of the machine. Near the buter end of this rod is fastened an arm 79 which is connected as shown to a tre-adle 81. Power having been applied to the driving shaft 65 will throw the clutch members 69, 71 into engagement. This will cause rotation of the cam 59 and reciprocation of the upper carrier 19. As has been explained above, it is desirable that the carrier be' given two complete reciprocations and then brought through a pulley 83 depression of the treadle to rest. To accomplish this a gear 85 hav- H ing twice the number of teeth o fthe gear 61 meshes with said gear 61 and is provided with a projecting portion 87 which acts against a small roll on'the arm 75 .to throw out the clutch after two revolutions'of the shaft 65. The lower carrier rod 13 is yieldingly connected with a cam lever 89 by means similar to that connecting the rod 47 with the cam lever 49 comprising a collar 91, a coiled spring 93 and a second coll-ar on the lower end of the rod. The cam lever 89 swings about a stationary rod 95 and is held in contact with the cam 63 by a spring 97.

The illustrative machine is equipped with two pairs of carriers and with two box toe supports, the members of one set being larger than those of the other for the reason that two sets are usually sufiicient to take care of all the sizes in a case of shoes, the

smaller support and carriers being used, forv now ready for use.

ladies or childrens, andto provide supports and carriers of different shape than those' shown for use with counters or other stifif- "that, as has been stated above, each support, irrespective of its size or shape, is centered with respect to the paths of movement of the carriers. It will be understood that a set of several interchangeable supports are provided with each machine.

Inasmuch as the two supports and the two.

sets of carriers and their operating mechanisms are substantially alike, only one has been described in detail. To the other support, carriers, etc, reference numerals increased by one hundred have been applied in order to identify the corresponding parts.

In the operation of the machine the operator depresses the treadle 81 whereupon the shaft 65 makes two revolutions thereby causing the carriers to contact twice. In this way the upper carrier is given a preliminary load of stifiening material. The machine is The box toe blank may be operated upon either before or after it has .been incorporated in .the upper of a shoe. In the latter case the operator first draws back the leather tip, the lining and the reinforcing pieces as shown in Fig. 4.

In either case the box toe blank is placed on .the hollow support with its margin projecting'beyond the. rim of said support, and the treadle is depressed. The carriers first grip the box toe blank to impregnate it with stiflening material as has been described. After they hag separated, the blank is removed. The carriersthen come together so as to load the upper carrier, and finally come to. rest in the position shown. Meantime the operator has picked up a new blank and is ready to present it on the support and depress the treadle again.

' Although the invention has beendescribed in connection with a particular machine, it

should be understood that the invention'is not limited in the scope of its application to ,the particular machine which has been .shown and described.
